AAA Industrial Co., Ltd produces the JW1AFSN-B-DC18V-F, a one-form-C power relay with very high load switching capabilities. It is ideal for applications where fast switching is required and where the load current could exceed two amps. It is an essential part of electrical systems in many industries, ranging from automotive, domestic and industrial control to computer automation, power systems and telecommunication systems.

Application Field:

The JW1AFSN-B-DC18V-F is suitable for use in electrical control systems in many industries. Its ability to quickly switch a large load current makes it perfect for large motor control, switchgear, switchboard and automatic production systems. It can also be used in automotive applications, such as starting, lighting and ignition systems. It can also be used to control pumps, cooling fans and domestic appliances such as refrigerators, washing machines and air conditioners. It is also used in applications such as computer workstations, telecommunications systems and power systems.

Working Principle:

The JW1AFSN-B-DC18V-F is a type of latching relay. This means that it has two sets of contacts which are "memorised" when an initial voltage is applied across its coil, allowing large momentary currents to be switched at the same time. The relay contacts are opened or closed when the voltage across the coil is greater than the nominal value of the voltage. When the voltage across the coil is below the nominal value, the relay will latch, and remain in operation until the voltage is again greater than the specified value.

The JW1AFSN-B-DC18V-F has a high current capacity of up to 20 Amps. Its wide voltage range of 6 to 24V DC and its high contact rating make it suitable for many applications. It has a dielectric strength of 500V AC between the coil and contacts and an insulation resistance of 100 megaohms. The mechanical life of the relay is at least 2 million operations.

Safety Considerations:

When using the JW1AFSN-B-DC18V-F in applications involving electric shock hazards, certain precautions should be taken. The relay should be securely mounted in an insulated enclosure to ensure that the contacts are not exposed to live electrical parts. The enclosure should be sealed with an appropriate degree of protection (IP65 or higher). The coil should not exceed the specified voltage, and it should be adequately rated and protected from surges and short-circuits. The relay should not be used in hazardous atmospheres where explosive gases and dusts are present.

The JW1AFSN-B-DC18V-F is a high current, latching relay that is suitable for use in a wide range of applications. Its fast switching and high current capability make it an ideal choice for electrical control systems in many industries. It is important, however, to ensure that the relay is appropriately rated and mounted to ensure it operates safely.
